A lever of negligible weight is loosely fitted onto a 75-mm-diameter fixed shaft. It is observed that the lever will just start rotating if a 3-kg mass is added at C. Determine the coefficient of static friction between the shaft and the lever.
a liquid-vapor mixture of 5kg of water with a quality of 0.75 and a pressure of 5bar is expanded in an isobaric process
the combustion products in an internal combustion engine undergo an expansion process from an initial volume of 0.007
consider axial viscous flow in a long annular pipe driven by a pressure gradient with an inner solid rod of radius ri
consider a well-insulated steam turbine. the inlet steam is at 5.0 mpa and 900oc. the exit pressure is at 200 kpa.
Consider the pharmaceutical product. Prior to finalizing the manufacturing process, test trials are performed to experimentally determine the depen- dence of the shelf life of the drug as a function of the sterilization temperature.
An inventor claims to have devised a refrigeration cycle operating between hot and cold reservoirs at 300 K and 250 K, respectively, that removes an amount of energyQC by heat transfer from the cold reservoir that is a multiple of the net work inpu..
The plastic stress-strain curve for the material is given by ( σ = 500 ε 0.25 MPa). The tube is subject to axial load F and internal pressure p so that the stress ratio σθ/σz = 3.0 at all times. The deformation continues until the effective stress..
